STOVE QOMPANY, OF GARDNER, MASSACHUSETTS, A CORFORATION 0F MASSACHU-TANK FOR OIL-STOVES.

Specification of Letters Patent.

Patented May 9, 1916.

Application filed November 12, 191%. 1 Serial .rTo. 571,761.

To all whom it may concern Be it known that I, FRED E. WHITE, a citizenof the United States, residing at Gardner, Massachusetts, have inventedcer tain new and useful Improvements in Tanks ior Oil-Stoves, of whichthe following is a specification.

This invention relates to liquid holding tanks and consists in providinga glass insert for the end of such a tank.

The invention is designed primarily for use on the cylindrical tanksforming the fuel reservoir on oil stoves, although its use is by nomeans limited to this.

The invention is illustrated in the accompanying drawings in which;

Figure 1 is perspective view of a cylindrical tank with a glass insertin one end; llig. 2 is a cross section through a diameter of the tankend with its glass insert; Fig.

is a modification.

In the drawings the numeral 1 indicatesthe tank, the end piece of thetank, and

' this edge 8 and the flange l, a strip of lead or other easilymalleable metal. 9 is forced until it bears upon the ridge 7 and firmlyseats this ridge against the seat The pressure exerted on the leadslightly bulges the flange l, as shown at 10, which acts to more firmlyhold the lead in place.

It will be observed that the periphery of the glass disk in front of theshoulder is slightly tapering toward the front and that the flange 4tapers upwardly normally toward the front and hence the lead packingwould normally, were it not for the bulge 10 be of practically V-shapeand with nothing to hold it in place against undue pressure as it woulddepend wholly upon frictional contact. By pressing in the lead howeverto make the bulge 10, it will be observed that a pocket is formed whichallows for an accumulation of lead of greater thickness in the centerline of the pocket than the mouth of the space through which the lead isinserted and hence the lead ispositively prevented from being withdrawnand at the same time the connection made is absolutely an oil tight one.

1 do nbt limit myself to the location of the glass 'dislc"concentrically of the end of the tank for as shown in Fig. 3, it may bearranged eccentrically nearer the bottom and this will enable the bottomof the tank to be observed and the exact quantity in the tank seen.These tanks are usually filled from the bottom and another advantage isderived from the eccentric arrangement in that when the tank is invertedto be filled more accurate filling may be effected due to the nearnessof the disk to the top of the tank when inverted.

I do not limit myself to the use ofthe disk of in the end of the tankthough I prefor this and it may be located in the top 01' side of thetank.

What I claim is:

A fuel tank for oil stoves having end walls with an inturned flange theinner periphery of said flange being substantially concave, a glass diskfitting against a shoulder on the flange on one face, said disk having aperipheral projection and a space toru'led between the periphery of theglass and the concavity of the wall and a packing within said spaceadapted to lock the glass and flange together, said packing being withinthe parallel lines of the face of the glass, substantially as described.

In testimony whereof, I allix my signature in presence of two witnesses.
